One long-standing idea is that the amygdala consists of an evolutionarily primitive division associated with the olfactory system (cortical, medial and central nuclei) and an evolutionarily newer division associated with the neocortex (lateral, basal, and accessory basal nuclei).tructural and/or functional changes in the amygdala are associated with a wide variety of psychiatric conditions in humans. Included are various anxiety disorders (PTSD, phobia, and panic), depression, schizophrenia, and autism, to name a few.
For example, neuroimaging studies indicate that the amygdala and orbitofrontal cortex are common brain structures involved in the recognition and processing of facial expressions representing a variety of emotions (e.g., fear, disgust, sadness, happiness, and anger); both structures are activated by the perception of different emotional faces (Del-Ben et al., 2008).
